SPECIFICATION forming'part of Letters Patent No. 292,924, dated February 5, 1884. Application filed April 17, 1883. (No model.)

T0 [6 whom it may concern.-

Be it known that we, OHARLEs J. LEAon and ALLEN OLDs, citizens of the United States, residing at Hartford, in the county of Van Enron and State of Michigan, have invented certain new and useful Improvements in Driving Gear for Traction-Engines; and we do declare thefollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art towhich it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

Our invention relates to traction or road engines; and the novelty consists in the construction and arrangement of parts, and in the adaptation of such parts in their relation to each other, as will be more fully hereinafter set forth, and specifically pointed out in the claim.

In the accompanying drawings, Figure l is a transverse vertical section of my device; Fig. 2, a side elevation with a portion removed or detached; Fig. 3, a top plan view, and Fig. 4 a detail.

' Referring to the drawings, in which similar letters of reference indicate like parts in all the figurcs,-A represents the boiler, having secured to each side thereof bearing-plates A A B, the steam-cylinder,,l) the piston-rod G the pitman, and E the crank-shaft, of an ordinary engine. well-known and approved construction, forn1- ing of themselves no part of this invention.

The crank-shaft E is journaled transversely to the longitudinal plane of the boiler parallel with and directly above the axes of the driving or riding wheels, which will be described. It carries an ordinary fly, or balance wheel, and carries also a rigid pinion, j, which meshes with a geanwheel, F. This gear-wheel Fin turn meshes with a larger gear-wheel, G, having openings i, in which is journaled at opposite points two beveled pinions, H, each of which is in constant mesh with two bevelgears, I and J, as shown. The outer gear, J, is rigid with the axle K,- with which is also These parts may be of any (3 rigidly hung the drive-wheel K. The bevelgear I is rigid upon a sleeve, L, which passes through the boiler and bearing-plate A, and upon this sleeve is rigidly hung the opposite drive-wheel; L, a proper screw-nut, ac, operating on the end of the axle K opposite the drive-wl1eel K, to secure the whole together. It will thus be'observed that the axle K is journaled loosely in the sleeve L and. bearingplate A, and that the said sleeve L is journaled in the boiler and bearing-plate A This being the construction and arrangement of the partsaccordingto our invention, and it being understood that M designates the guidewheel, which may be deflected in either direction at will by proper mechanical appliances, the following motions and combinations of motions will be found to result: The wheel G, receiving its motion from the crankshaft E through the connections described, transmits its motion through the pinionsH and bevel-gears J and I equally to the drivewheels K and L from oneside of the engine, and this equal distribution of power will continue so long as the engine moves in a direct line. It will also be observed that when the direction of the engine is changed by the deflection of the guide-wheel M, the wheel G continues its work, but that the wheels I and J change their positions relatively to each other, allowing either of the wheels K or L to move faster than the other, according to the direction of the guide-wheel.

The engine may be turned in either direction, each drive-wheel having an independent motion, and the power from the crank-shaft acts uniformly and efficiently, whichever way the turn is made.

It will of course be understood that the pin ions H are of the same size and conformation, as also are the wheels I and J.

- Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent of the United States, is-

i The road-engine herein described, consisting of the boiler A, having the bearing-plates A A and the sleeve L, passing through the boiler and engaging the bearing A and provided with the rigid gear-wheel I and drivewheel L, the axle K, journaled in the sleeve In testimony whereof we affix our signzitures and bearing A, and having the rigid gearin presence of two witnesses.
